Nowadays, the majority of businesses have incorporated artificial intelligence (AI). Despite its advantages, AI can make faulty business decisions that expose both the businesses and their end consumers to risk, which can have a considerable impact and happen at the most random times.

Computer vision (CV) is an area of artificial intelligence that analyzes and responds to data from visual inputs like digital photos and videos. While CV has become one of the most widely used technologies worldwide, CV models are not immune to threats. A promising model might be a significant liability if it fails to function as planned. How we obtain and use CV models is important since images are exceptionally high-dimensional and require complex models that are  prone to failure.

Whether for diagnosing cancer or determining how to behave in risky traffic conditions, CV models bear the world’s responsibility on their shoulders. Unsurprisingly, machine learning (ML) algorithms often make unethical, clearly incorrect or biased conclusions. Obtaining a CV model is difficult in and of itself, given only a tiny percentage of generated models are deployed in continuous production contexts.

There are common issues in developing CV models such as inconsistent methods for model deployment and design of the CV systems, lack of documentation, or security issues. Taking proactive actions  is crucial to avoid failures. This article gives advice on how to manage those risks in CV models. Platforms make deploying the CV model and tracking its lifecycle more accessible to designers and other CV system specialists.

Tip 1: Consistency

Consistency is one of the most critical requirements. The level of understanding all departments within the company have about consistent procedures is crucial for generating the algorithm. It is also considerably simpler for legal and risk-management teams to evaluate risks when there are clear criteria for creating training datasets, labeling data, training and evaluating models, and all other phases of CV system design.

Tip 2: Documentation

Comprehensive documentation allows developers and data engineers to streamline model evaluations. In the event of a data scientist replacement, a unified document is the only means for the new data scientist to fully analyze, manage, and understand the CV model.

Tip 3: Model production readiness

Production-ready models must be extensively evaluated to ensure they are not too sensitive, perform well across data subsets, and successfully handle distribution changes and aberrant inputs. All these features should be automatically tested to guarantee that models meet your standard definition of production-ready. Implementing a production-ready model saves you the time it would take to construct a model from scratch while also allowing you to integrate the model via simple API requests.

Tip 4: Model protection in real time

Machine learning algorithms are renowned for producing confident but erroneous predictions on data points containing outliers, missing values, previously undiscovered categories, and other anomalies. CV models should be protected from unexpected inputs by flagging, blocking, and imputing particular inputs that your model is not prepared to handle. To detect faulty data points automatically when data flows in during production, the designer has to enhance the CV model by retraining and redeployment procedures to prevent incorrect inputs to the model.

Tip 5: Model compliance evaluation

Ensuring CV models comply with regulations prior to releasing to the public is as important as it is time-consuming. A good practice is to choose a compliance-focused test, synthesize the findings into a report, and keep an audit track of the models.

Tip 6: Model monitoring

Because data streams are constantly changing and developing, an already trained model may not perform effectively today. Once the model is in production, conduct continuous testing for monitoring and notifying on distribution drifts and unusual inputs that might cause your model to fail. It is ideal to be able to recognize when it is time to retrain the CV algorithm and automate model failure root cause investigation. Tracking semantically meaningful picture data components should be provided to handle highly challenging CV monitoring difficulties. Continuous monitoring of the models in production is needed to spot errors, determine when a model needs to be retrained, and automate root cause investigations of model failure.

Tip 7: Adversarial attacks

CV models can be tricked by adversarial input (adversarial assaults) and may be misled by malicious actors into producing inaccurate predictions with nearly undetectable modifications to the information. Using the collection of black-box adversarial attack tests enriches the data, enhances the training algorithms, and finds the most robust candidate models to harden the model against such faults.

Tip 8: Stress Testing

To be sure CV models function correctly with various forms of data, check explicitly for data transformation invariance, resistance to noise and assaults, and generalizability across important picture attributes. If the CV system’s robustness is inadequate, acquiring the correct data is needed to improve it. This process includes creating the appropriate synthetic data and augmentations. It aids in communicating the product’s restrictions to consumers, thus ensuring transparency and safer use.


To manage risk and develop the CV model, some companies give solutions for creating, deploying and testing the CV model. One end-to-end solution is proposed by Robust Intelligence. Their platform provides tools for conducting tests to automatically identify potential issues and suggest improvements for model production readiness. Their AI stress testing algorithm rigorously tests the CV models to ensure they are not overly sensitive, function well across subsets of data, and manage distribution shifts and abnormal inputs. Their AI testing algorithm rigorously tests the CV models to ensure they are not overly sensitive, function well across subsets of data, and manage distribution shifts and abnormal inputs. They use AI Testing to observe and warn about distribution drifts and abnormal inputs, which may be driving the CV model to fail.

Another company, Lakera, makes it possible to systematically test under which conditions the CV model works when it fails and creates a risk assessment of the system before it is used. This platform provides procedures to identify and export failure cases for improved data collection, labeling, and retraining. This platform compares models quickly and efficiently to ensure that the best performing model is always selected. Furthermore, you can identify data quality issues to avoid model bugs and biases and encounter optimal image augmentation techniques for model training.

CV systems have been used in various applications, including security, law enforcement, and personal gadgets, and it is evident these systems may provide incorrect results. It could be an issue if a promising model poses as a liability and fails to function as planned. On the other hand, diagnosing and comprehending the actual reasons for model failures are complex undertakings since contemporary CV systems rely on complex black-box models with difficult-to-interpret behaviors. To avoid risks in CV models, the proposed pieces of advice are given above.
